Geothermal Gases

  • Graeme L. Lyon
Part of the Marine Science book series (MR, volume 3)


The major components of geothermal gases are steam and carbon dioxide. At high temperatures, chemical and isotopic equilibrium will be established, but as the gases cool, equilibrium conditions are not maintained. Interaction of gases with wet sediments will result in a gas mixture consisting of methane, hydrogen, nitrogen and rare gases.
